Damn, they're ending about now...
The model 00 boards may be Microswitch?, they are most likely not buckling spring. Maybe sheet dome like the second generation PCjr or later 5085 / 6150 'boards (see
here).
The P/N
6016732 (model "__ _"!) and
6016730 look more likely to be clicky, though they don't seem to have cables...
The part numbers don't show in the announcement letter database, but vendors seem to think they're for the 3290 (can I stop talking about that thing?). The other suggestion of them being for the 3194 I'm not so sure about, as the
initial letter for that seems late [June '86, compared with that 6016732 dated 47[th week of]- 1983] and the letter speaks only of 102s and 122s.
